Re: st: Stata 11 Announcement

- Finally "bold and italic text, Greek letters, symbols,
superscripts, and subscripts on graphs". "Thank You" - and that is
from a biologist's point of view.
- And just a few days back I was thinking that I will not upgrade my
Stata if it is going to come with those 50 pounds of reference books.

One more thing... !!!!!

That is so Steve Jobish.

Following long tradition, we are informing Statalist first:
Stata 11 begins shipping Monday, July 27.
Orders are now being accepted at http://www.stata.com
Below are some highlights from the release.
----------------
Factor variables
----------------

Probably the highlight of the release is factor variables, if only
because
everyone is going to be using them. Stata itself now deeply
understands

Stata itself forms the necessary indicator variables. NO NEW
VARIABLES

ARE CREATED IN YOUR DATA.

In the above, # means interaction, and ## means factorial
interaction, so
A##B is equivalent to A B A#B. Asterisks would have looked better,
but *
is Stata's varlist wildcard indicator, and factor variables are now
just

part of varlists, so * and # had to coexist. Anyway, interactions are
much more like Kronecker products than like multiplication.

By the way, I typed -i.- everywhere above, but you can type, for
example,

-sex#group- and Stata will know that you mean -i.sex#i.group-.

You can form interactions of factor variables with continuous
variables,

and continuous variables with continuous variables, by using the -c.-
prefix:

That is useful for understanding exactly what the notation produces.
--------
Graphics
--------
You can now put bold and italic text, Greek letters, symbols,
superscripts, and subscripts on graphs. What more is there to say?
----------
Statistics
----------
There are many new statistics in Stata 11, including
o multiple imputation
o competing-risks survival-time regression
o GMM estimation with user-specified moment functions

There is so much to say about multiple imputation that Stata's new -
mi-

command gets its own manual.
See http://www.stata.com/stata11 for details.
------------------------------
Graphical user interface (GUI)
------------------------------
New GUI features include
o Variables Manager
Edit names, labels, display formats, storage types, notes, and
value labels. Those with many variables can use a filter to
see a selected subset of variables.
o Data Editor
Live view onto your data, filters, data snapshots, and more.
o Do-file Editor for Stata for Windows
Syntax highlighting, code folding, and no limit to file size.
I admit that I do not use GUI features often, but the new Variables
Manager does indeed make things easy. Others here tell me that the
new Data Editor will be the most popular interface feature because
you can now leave it open while you perform your analysis, and changes
are reflected instantly in it. You can even perform all your data
management from within the Data Editor, and do so in a reproducible
manner because it issues Stata commands for all changes.
-----------
Programming
-----------

Mata now includes full object-oriented programming facilities:
classes,

inheritance, constructors and destructors, public/private/protected
declarations, virtual functions, and more. Just as in Java, code is
fully compiled, so there is no speed penalty for using it.
-----------
PDF manuals
-----------

Stata's manuals now ship in PDF format with every copy of Stata.
All the
